JOSEPH DORIN, OF ROUEN, FRANCE.

APPARATUS FOR HOISTING PIECES OF FURNITURE AND SIMILAR OBJECTS THROUGH WINDOWS OF UPPER STORIES OF BUILDINGS.

To all whom it may concern:

Be it known that I, J osnrrr DORIN, a citizen of the French Republic, residing at Rouen, of the Republic of France, have invented certain new and useful improvements in an apparatus for hoisting pieces of furniture and similar objects through the windows of upper stories of buildings, of which the following is a specification.

This invention relates to an apparatus for lifting pieces of furniture and similar objects through the windows of the upper stories of buildings.

In the accompanying drawings the invention is shown by way of example.

Figure 1 shows the apparatus in front elevation mounted in the window. Fig. 2 is a side view of the apparatus, the window being shown in vertical section. Fig. 3 is a view similar to Fig. 1 showing another form of construction of the apparatus. Fig. 4- is a vertical section of Fig. 3.

The apparatus essentially consists of two vertical supports which are each composed of two parts, a lower tubular part 4 and an upper rod 6. The tubular part 4. has a nut 5 at its upper end and the lower part 7 of the rod 6 is threaded so that it can be screwed into said nut 5. The upper end of the rod 6 is fork-shaped. The lower ends 2 of the supports are placed upon the window sill so that they are slightly inclined toward the outside, the lower ends of said supports bearing against the lower cross frame 2 of the window. In the upper forkshaped end 8 of each of the supports 6 a rack 15 is placed which stands perpendicular to the lintel 3 of the window. The racks 15 have each at the front end and in the lower edge a notch 12 which engages with the bottom of the fork-shaped end 8 of the corresponding support. Shackles 9 are fixed upon the racks 15 by means of clamping screws 10 which engage with the teeth 11 of the racks. The shackles have a horizontal threaded boring at the upper end into which horizontal screw spindles 13 are screwed which have clamps 14 adapted to bear against the front and rear of the lintels 3 in order to securely fix the apparatus in the window. The racks have at their front ends upwardly projecting U-shaped extensions 17 in which the cross bar 16 is mounted at the middle of which a winch 18 is suspended.

Specification of Letters Patent.

Application filed April 23, 1912. Serial No. 692,678.

Patented Nov. 26, 1912.

It seems not to be necessary to further explain the function of the apparatus as it is absolutely clear from the foregoing description and from the accompanying drawings.

The apparatus can be adjusted according to the thickness of the wall owing to the racks which are carried by the upper end of the supports.

According to the form of construction shown in Figs. 3 and 4 vertical stays 19 are mounted in the U-shaped extensions 17 of the racks 15. These stays are either made of wood or of metal. In the upper ends 19 of said vertical stays 19, notches are provided in which the cross bar 16 is mounted. These stays 19 further have lugs 20 into which screw spindles 20 are screwed which bear with their inner ends against the wall or the lintel of the window. These screw spindles 20 have nuts 21 the position of which upon the spindles is adjusted according to the distance betweenrthe stays 19 and the wall. Eyes 22 are fixed in the rear surface of the cross bar 16 and chains 28, 2 1 are attached to these eyes. The chain 23 is placed around the screw spindle 1 1 of the left hand side of the rack while the chain 24; is guided around the spindle 14 of the right hand side of the rack so that said chains cross each other and securely maintain the cross bar 16 in its position. The free ends of the chains are attached to one of the links of the chain. The winch 18 is mounted upon the middle cross bar 16. The apparatus is mounted in the same manner as the apparatus shown in Figs. 1 and 2.

I claim:

-1. An apparatus for hoisting pieces of furniture and other similar objects through the windows of buildings, comprising in combination two adjustable supports mounted upon the window sill, upper fork-shaped ends of said supports, horizontal racks mounted in said fork-shaped ends, shackles in front of and behind the wall mounted upon the said rack, set screws on the lower end of said shackles fixing the shackle upon the rack, horizontal internally threaded sleeves at the upper ends of said shackles, screw spindles having clamps at their inner ends screwed into said horizontal sleeves, a U-shaped upwardly projecting extension at the front end of each rack, a cross bar mounted in said U-shaped extensions and a winch suspended to said cross bar substantially as described and shown and for the purpose set forth.

2. An apparatus for hoisting pieces of furniture and other similar objects through the windows of buildings, comprising in combination two adjustable supports mounted upon the window sill, upper fork-shaped ends of said supports, horizontal racks mounted in said fork-shaped ends, shackles in front of and behind the wall mounted upon the said rack, set screws on the lower end of said shackles fixing the shackle upon the rack, horizontal internally threaded sleeves at ,the upperv ends of said shackles, screw spindles having clamps at their inner ends screwed into said horizontal sleeves, a U-shaped upwardly projecting extension at the front end of each rack, a vertical stay attached to said cross bar and guided each around the screw spindles of the rack at the other end of the scaffolding, substantially as described and shown and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
